Which of the following ALTER DISKGROUP commands does not use V$ASM_OPERATION to
record the status of the operation?
A. ADD DIRECTORY
B. DROP DISK
C. RESIZE DISK
D. REBALANCE
E. ADD FAILGROUP

　　The ADD DIRECTORY command is not likely to use V$ASM_OPERATION to track its progress,
because this operation adds only a small amount of metadata-a directory object-to the disk group 
and takes a minimal amount of time to complete.The V$ASM_OPERATION view provides the status
of long-running ASM operations.
